Combined density, flash point and boiling point information helps laboratories align safety measures and method parameters with the behaviour of the solution throughout environmental and chromatographic PCB work.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/en-be\/collections\/chromatography-standards\"\u003eChromatography standards (GC, HPLC, pesticides)\u003c\/a\u003e, in \u003ca href=\"\/en-be\/collections\/analytical-standards-and-reference-materials\"\u003eAnalytical standards \u0026amp; reference materials\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAssay (in isooctane): 100 µg\/ml\u003c\/li\u003e\n\u003cli\u003ePack size: 1 ml glass\u003c\/li\u003e\n\u003cli\u003eDensity: 0,69 g\/cm³\u003c\/li\u003e\n\u003cli\u003eFlash point: −12 °C\u003c\/li\u003e\n\u003cli\u003eConcentration: 100 µg\/ml\u003c\/li\u003e\n\u003cli\u003eSolvent: Isooctane\u003c\/li\u003e\n\u003cli class=\"lx-tis-li\"\u003eTechnical Information Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/api.carlroth.com\/medias\/SDB-1X0Y-DE-EN.pdf?context=bWFzdGVyfHNlY3VyaXR5RGF0YXNoZWV0c3wzMzY0MDF8YXBwbGljYXRpb24vcGRmfGFHTTFMMmhpTWk4NU1qSTJPRE0xTXpZeE9ESXlMMU5FUWw4eFdEQlpYMFJGWDBWT0xuQmtaZ3xhNzZjNTU0OGMyMDAxOTAyM2U0ZTYwMjZjMDA1YWM5MTU1ZDkwYWVkMmRkODdiZDQ1YTNjOTQxYTMzOGNkYjk3\" target=\"_blank\" rel=\"noopener noreferrer\" style=\"display:inline;vertical-align:middle\" title=\"Technical sheet PDF\" aria-label=\"Technical sheet PDF\"\u003e\u003cimg class=\"sds-icon\" src=\"https:\/\/img.icons8.com\/color\/48\/pdf.png\" alt=\"PDF\" width=\"18\" height=\"18\" style=\"width:18px;height:18px;max-width:18px;margin:0;padding:0;display:inline;vertical-align:middle;border:0;\"\u003e\u003c\/a\u003e\n\u003c\/li\u003e\n\u003cli class=\"lx-tis-li\"\u003eSafety Data Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/api.carlroth.com\/medias\/SDB-1X0Y-DE-EN.pdf?context=bWFzdGVyfHNlY3VyaXR5RGF0YXNoZWV0c3wzMzY0MDF8YXBwbGljYXRpb24vcGRmfGFHTTFMMmhpTWk4NU1qSTJPRE0xTXpZeE9ESXlMMU5FUWw4eFdEQlpYMFJGWDBWT0xuQmtaZ3xhNzZjNTU0OGMyMDAxOTAyM2U0ZTYwMjZjMDA1YWM5MTU1ZDkwYWVkMmRkODdiZDQ1YTNjOTQxYTMzOGNkYjk3\" target=\"_blank\" rel=\"noopener noreferrer\" style=\"display:inline;vertical-align:middle\" title=\"SDS PDF\" aria-label=\"SDS PDF\"\u003e\u003cimg class=\"sds-icon\" src=\"https:\/\/img.icons8.com\/color\/48\/pdf.png\" alt=\"PDF\" width=\"18\" height=\"18\" style=\"width:18px;height:18px;max-width:18px;margin:0;padding:0;display:inline;vertical-align:middle;border:0;\"\u003e\u003c\/a\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Carl Roth","offers":[{"title":"1 ml \/ 1 piece","offer_id":56125731799372,"sku":"1X0Y.1","price":73.0,"currency_code":"EUR","in_stock":true},{"title":"1 ml \/ 6+ pieces","offer_id":56125731832140,"sku":"1X0Y.1","price":69.35,"currency_code":"EUR","in_stock":true},{"title":"1 ml \/ 24+ pieces","offer_id":56125731864908,"sku":"1X0Y.1","price":65.7,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/1TP6-SF-1000Wx1000H.jpg?v=1766405383"},{"product_id":"pcb-6-1x10-1x10","title":"PCB 6, 500 µg\/ml in isooctane, 1 ml, glass","description":"\u003cp\u003ePCB 6 is an analytical standard solution at 500 µg\/ml in isooctane, delivered in a 1 ml glass pack for laboratory chromatography.

In environmental laboratories, PCB 15 standards help verify chromatographic behaviour, establish response factors and support reliable quantification of this congener in complex samples. The material from manufacturer Carl ROTH is intended for GC-based residue and contaminant workflows that depend on a clearly defined mono-congener level in isooctane. Use with compatible glassware, controlled storage where indicated, and validated injection protocols to maintain concentration integrity throughout analytical sequences.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/en-be\/collections\/chromatography-standards\"\u003eChromatography standards (GC, HPLC, pesticides)\u003c\/a\u003e, in \u003ca href=\"\/en-be\/collections\/analytical-standards-and-reference-materials\"\u003eAnalytical standards \u0026amp; reference materials\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAssay (in isooctane): 100 µg\/ml\u003c\/li\u003e\n\u003cli\u003ePack size: 1 ml glass\u003c\/li\u003e\n\u003cli\u003eDensity: 0,69 g\/cm³\u003c\/li\u003e\n\u003cli\u003eStorage temperature: +4 °C\u003c\/li\u003e\n\u003cli\u003eConcentration: 100 µg\/ml\u003c\/li\u003e\n\u003cli\u003eSolvent: isooctane\u003c\/li\u003e\n\u003cli class=\"lx-tis-li\"\u003eTechnical Information Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/api.carlroth.com\/medias\/SPEZ-1X14-EN.pdf?context=bWFzdGVyfHNwZWNpZmljYXRpb25zfDEwMzA2MnxhcHBsaWNhdGlvbi9wZGZ8YURSakwyZ3dNeTg1TWpVME5UY3pPRGs1T0RBMkwxTlFSVnBmTVZneE5GOUZUaTV3WkdZfGMxY2MyNjkzMzA5MGJhM2I3NmQ5NTc2ZGJiZmI5Y2NmYmFmYjk2ZTNiN2Q2MDE0MjlkODJjZjMzZjc5MDY4ZGU\" target=\"_blank\" rel=\"noopener noreferrer\" style=\"display:inline;vertical-align:middle\" title=\"Technical sheet PDF\" aria-label=\"Technical sheet PDF\"\u003e\u003cimg class=\"sds-icon\" src=\"https:\/\/img.icons8.com\/color\/48\/pdf.png\" alt=\"PDF\" width=\"18\" height=\"18\" style=\"width:18px;height:18px;max-width:18px;margin:0;padding:0;display:inline;vertical-align:middle;border:0;\"\u003e\u003c\/a\u003e\n\u003c\/li\u003e\n\u003cli class=\"lx-tis-li\"\u003eSafety Data Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/api.carlroth.com\/medias\/SDB-1X14-DE-EN.pdf?context=bWFzdGVyfHNlY3VyaXR5RGF0YXNoZWV0c3wzMzYxOTZ8YXBwbGljYXRpb24vcGRmfGFEQTRMMmhtTWk4NU1qSTJNek0wTURFeE5ESXlMMU5FUWw4eFdERTBYMFJGWDBWT0xuQmtaZ3w0MDMwN2M5YzU0ZmJkNjQzMzQ5OTNiNjhmY2Q1NDkxYWM2MDEwMTQ0YWVlYTg4NDkyOWRmMmUzOTY1NDFkOGVh\" target=\"_blank\" rel=\"noopener noreferrer\" style=\"display:inline;vertical-align:middle\" title=\"SDS PDF\" aria-label=\"SDS PDF\"\u003e\u003cimg class=\"sds-icon\" src=\"https:\/\/img.icons8.com\/color\/48\/pdf.png\" alt=\"PDF\" width=\"18\" height=\"18\" style=\"width:18px;height:18px;max-width:18px;margin:0;padding:0;display:inline;vertical-align:middle;border:0;\"\u003e\u003c\/a\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Carl Roth","offers":[{"title":"1 ml \/ 1 piece","offer_id":56125732454732,"sku":"1X14.1","price":73.0,"currency_code":"EUR","in_stock":true},{"title":"1 ml \/ 6+ pieces","offer_id":56125732487500,"sku":"1X14.1","price":69.35,"currency_code":"EUR","in_stock":true},{"title":"1 ml \/ 24+ pieces","offer_id":56125732520268,"sku":"1X14.1","price":65.7,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/1TNY-SF-1000Wx1000H_cbf6af5d-84bf-4eba-92e6-b780d1d7b5c4.jpg?v=1766405393"},{"product_id":"pcb-12-1x19-1x19","title":"PCB 12, 500 µg\/ml in isooctane, 1 ml, glass","description":"\u003cp\u003ePCB 12 is a single-congener reference solution at 500 µg\/ml in isooctane, prepared for quantitative work in environmental analysis and gas chromatography.
